Application filed `March 16, 1321,. Serial No. 452,648.

To all w 710mt may concern .Be it known that we, A.Rfrnun L. DUNCANJ and @iraniens E. Foiinr, Acitizens of the lUnited States, residing at' Oaklandz in the county of Alameda andr State of California, have invented'new and useful Improvements in Can Solder Horns, of which the follow- This invention relates tocan foriningmachinery, and particularly pertains to a -solder liorn,upon which the body portions of the 0211i are. formed. l Y y It is common practice to provide can Y body forming `machines with floating horns,

oyer which the cylindrical. bodies may loe positioned and ,carried longitudinally theren of, and itiS. .the principal4 .object .of the present invention t0" povide a support for;y the horn, which will insure that thehorn is at allY timv'esfl supported, while permitting the cansftor in'ove without interruption therealoiig without damage .to 'the lap of the can y beay'dueto, ure weight Qt the. here,

lThe present invention vconteinplates 1the ,use of a yhori,zontally' disposed horn operatively positioned'relative .to suitable feedI means, by which afsuccession of can bodies may be ymoved Valong the horn and a rotary ,support adapted to contact with the horn at points between thecans to thereby insure that the horn will`loe at all times supported.

" The invention yis illustrated by way of eXainplein the accompanying drawings, in

LF'igur'e 1 is a fragmentray view. showing thepresent invention.`

Fig. 2'is an end view showing the arrangement of ,parts of the present invention.

Referring more particularly tothe draw- 10 indicates a bed plate supported at its opposite ends by legs 1l, o ne set of which is not indicated in the drawings. Standards 12 extend upwardly from thebfed plate and carry sprocket shafts `13. `rl`liesershafts are `fitted with sprockets .14 over. which a `sprocket feed chainy 15 is led. The chain 15 is formedwitli flights l'tiwhich are'inounted upon certain of the links of the chain, and are'disposed in equal spaced relation to eachother. It is` tobe understood that the length of theu bed plate and the distance from .the center to center of the sprocket wheels may loe ,as desired.

. Thelower run ofthe sprocket chain moves horizontally and parallel troia solderhorn secured.v These members havefouter aouate faces 'disposed to` substantially 'conform Ito the inner circumference of the can lotfdies` 18 moving therealong` y y u ln order to continuously support the outer end of the horn at the same time to permit the cans to move tlierealongl';` without interlruption", a star Wheel'22 is provided. AThis Awheel is l.provided with avplurality of radial alrnis 23,' here shownas sX in nuiriloer.V The s g number of these ariiis andtheir^` ingular relation yto each other will depend upony the length of the can bodies Aandtheir spaced relation to each other while moving along the horn. The star wheel 'is mounted upon-a shaft 24;, journaled on the bed plate 1l() and disposed at right angles to the longitudinal axis of the horn. The outer ends ofthe radial arms 23 are fitted with rollers 25 carried on pins 26. The4 rollers move in .the saine plane with the longitudinal axis of the horn and the vertical transverse axis of the horn. This will cause the rollers to pass-directly beneath the transverse enter .of the horn and move .longitudinally thereof. l rThe star wheel is so proportioned and mounted above the lower face of thehorn.' For this purpose the arcuate block 20'is`secured be-' tween .the horn plates 19 andffornis a track along which the rollers 25 move. The een` ter of the arcof this Vlolozck is the rotating axis of the starfwheel.

lt is necessary to drive the star .wheel and the feed chain 15 in synchronism, and for that reason a drivev shaft l27 is provided. This shaft extends longitudinally of the bed plate 10 and is journaled v'Within bearings 2:8. A hevelgfear 29 is'fixed to this shaft, and is in mesh witli'a ,bevel gear 30 fixed upon. a

`as to cause the rollers to ,swing upwardly transverse shaft 31. VSprocket wheels .353 are mounted on this shaft. The sprocket wheel 32 carries achain 34 which .is led around ya (lriving` ysprocket 35 of thestar Wheel 22. The Strecke@ 3.3 @arnese latein 36 which is led around a sprocket 37 secured to the standard l2 at the end of the horn. This sprocket is mounted upon a shaft 38 parallel to the shaft 13 and acts through suitable transmission mechanism 39 to drive the sprocket 14e at the end of the horn in a reverse direction. Due to this transmission mechanism the lower run of the chain l will move in the direction of the arrow -C-, and the star wheel 22 will move in the direction of the arrow -b-.

ln operation of the machine, can bodies y are formed and placed on the horn 17, 'thereafter being moved down until they are engaged by the flights 16 ofthe feed chain l5. The can bodies'will then travel in the direction of the arrow cal/Ve will assume thatJ the feed chain and the star wheel have been properly adjusted and that they may move in synchronism. Reference to Fig. l will disclose the fact that the distance between the rollers 25 of the adjacent arms of the star wheel is greater than the length of a can body. This will permit a can body tobe moved along between these arms as their rollers engage the arcuate track 20. Attention is directedy to the fact that the arcuate bearing face of the member 2O is recessed relative to the lower edges of the plates 19 and the side members 2l. This produces an arcuate ychannel into which the rollers pass, and will thus prevent radial movement of the horn. As the can A moves forward, radial arm B will move from beneath the horn and radial arm C will travel along the arcuate face of the member 20 as it follows the can body A. A can body D will be following the radial arm C, and this will in turn be followed by the next adjacent radial arm E. rlhis sequence of operation will continue as the successive cans are fed along the horn and the star wheel rotates. i, n

It will thus be seen that the structure here disclosed pro-vides simple means for continuously supporting a solder horn and insuring the cans may be fed therealong without interruption.

While we have shown the preferred form of our invention, as now known to us, it

will be understood that various changes might be made in the combination, construction, and arrangement ofparts, by those skilled in the art, without departing from the spirit of the invention, as claimed.

Having thus described our invention, what we claim and desire to secure by Letters Patent is:
